The problem:
In the traditional marimbamusic of the Pacific coastof Colombia there are aset of tunings andpractices that remainlargely uncomprehended.
Tonal consonance for pure tones
Tonal consonance for complex tones
Tonal consonance associated to a particular timbre (DF ):
- Tonal consonance superposition principle- Timbre strongly depends on the spectrumα → Frequency ratio
Tonal consonance associated to the superposition of two complex tones with the same timbre:
Harmonic spectrum analysis: Six harmonics
α→ Frequency ratioDF (α) → Total dissonance
Harmonic intervals analysis
Marimba de chonta Timbre
Theoretical analysis IClosed pipes, strings without stiffness and rectangular bars
Theoretical & Experimental
All marimbas: Experimental
